RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 402,308, dated April .30, 1889. Application filed February 4:, 1889. Serial No. 298,684. (No niodel.)

To @ZZ whom it may concern:

Be it known that I, EDWIN M. CooKE, of Brooklyn, Kings county, and State of New York, have invented a new and useful lmprovement in Rail-Joints, of which the following is a full, clear, and exact description.

My invention is an improveinentin railjoints, and has for an object to provide a simple, durable, and easily-applied construction which may be cheaply made and which will be efficient and practicable in use.

The invention consists in the novel construction and combination of parts, as will be described and claimed.

In the drawingsfFigure l is a side view,

- Fig. 2 is a perspective view, Fig. 3 is a lonafter.

gitudinal section, and Fig. 4 a cross-section, of my improvement as in use; and Fig. 5 is a detail view of the wedge. y

The jacket A is preferably formed by roll. ing a plate of metal into the desired shape, which will be more fully described herein- In forming the jacket I goffer or corrugate itin such manner as to form the recesses for the wedges. I Inake the jacket of metal of equal thickness throughout, and it comprises the base-plate A', the edge portions A2 at the edges of base A', the goffers orcorrugated portions A3 forming the Walls of the wedge-recesses and the side plates, A4, such plates A4 itting against the opposite sides of the Webs of the meeting-rails B, and being perforated for the'passage of the fasteningbolts, as shown. It will be seen that the side plates, A4, donot extend up and bear under the treads of the rails, so that the pressure on such rails is borne wholly upon the base A of the jacket. `The strength of the jacket is materially increased by the goffering or corrugating, and such construction also results in for min g the ways or recesses for the wedges. The under side of the portion A3, forming the top Wall of the recess or Way C for the wedge D, is formed longitudinally parallel with the upper side of the base of rail B.

The Wedge D is formed of the sections d d', the former, cl, consisting of a base-bearing, and the latter, el', constituting the driving-section, the upper face of section CZ and the lower face of section d being beveled, the opposite sides of such sections being parallel, so that the section d will rest flat against the top of the railbase and the section d Will rest flat against the under face of the goifer A3, the beveled faces of sections d d bearing together, as shown, so that as the section d is moved longitudinally on section d Within the space between the rail-base and gofer A3,I effect a clamping together of such parts, as shown.

It will be understood that the sections d d are driven in reverse directions on opposite sides of the rails. After the section d has been properly driven itis secured to prevent it from moving back. This is preferably effected by forming the point of said section to extend, when driven up, slightly past the base of the section d, and to bend such point at d2 down along the base of section d to secure such parts, as will be understood from the drawings.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a rail-joint, the combination, with the rails and the jacket embracing the same, ways or Vrecesses being provided between the upper side of the base of the rail and the jacket, of the wedges fitting said ways or recesses and formed of sections CZ d', having each a straight and an inclined face, the section d being inserted in the Way, and the section d being driven up on such section d and secured, substantially as set forth.

2. The improved rail-joint consisting of the jacket havinga base-plate and provided with goffers or corrugations A3, having their under sides or faces formed on horizontal lines, whereby in operation such surfaces will be on lines parallel with the tops of the rail-base, and the Wedge formed in sections and adapted to bear between said goffers and t-he rail-base, substantially as set forth.

3. The improvement in rail-joints, substan-v tially as herein described, consisting of the rails, the jacket A, fitted thereto and formed with go'ers or corrugatons A3, having their 0f sections d, and bent at (Z2 down against the under sides formed in lines parallel with the bases of sections d, all substantially as and tops of the rails, and the wedges formed in for the purposes Specified.
